BYRON B. PHILLIPS, OF HUDSON, NEW YORK.

ICE-CONVEYER.

Specification of Letters Patent.

Patented Jan. 21, 1919.

Application filed .l'uly 3, 1917. Serial No. 178,451.

To all whom it may concern:

Be it known that I, BYRON B. PHILLIPS, a citizen of the United States, residing at Hudson, in the county of Columbia and State of New York, have invented a new and useful Ice-Conveyer, of which the following is a specification.

This invention has reference to ice conveyers, and while the invention, in whole or in part, may be used for conveying other materials than ice and is to be considered of sufficient scope to include such other ma terials the following description, for the sake of simplicity of expression, will refer to the use of the invention as an ice conveyer.

The object of the invention is primarily to load ice from an ice house into transportation vehicles such as freight cars or vessels, although the invention may be used in connection with wagons, trucks or similar vehicles, and its mode of action may be reversed so as to convey ice from vehicles into the ice house.

The conveyer is made portable and also of small depth so as to occupy a minimum of space outside of the icehouse and, for loading ice into vehicles, the action of the conveyer is largely automatic.

The invention provides an endless con veyer having suitable carrying flights with means for directing the blocks of ice onto the flights and other means for discharging the blocks of ice from the flights.

The several parts of the conveyer are of peculiar construction adapting them particularly for the service demanded: and, while the invention is an improvement upon Letters Patent No. 1,07 2,985, for a conveyer for handling ice, which patent was granted September 9, 1913, the present invention differs in many respects from the structure of the patent with the improved features greatly simplifying the construction and operation and improving the efficiency of the apparatus.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming a part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications come within the scope of the appended claims.

In the drawings Figure 1 is an elevation of what may be termed the front of the conveyer.

Fig. 2- is a side elevation, as seen from the right hand side of Fig. 1, and showing an ice house and a railroad car and some other parts in section. r

Fig. 3 is a section on the line 3-3 of Fig. 1, omitting the railroad car and indicating a part of the ice house in dotted lines.

Fig. 4: is a plan View of the telescoping chute used in connection with the conveyer.

Fig. 5'is a perspective view of a directionchanging means for ice blocks for delivering them to the chute or receiving them there from.

side thereof, the frame. being longer than wide, are posts 2 rising to a sufficient height for the purposes of the invention. These posts are connected at the top by a crosspiece 3 and may be of such construction as to provide a firm carrier for parts to be described. That long side of the basic member upon which the posts 2 are erected may be considered as the rear side of the conveyer structure, and the other side may be termed the front side. The rear side of the con veyer is, when the structure is in operation, placed close to a doorway or opening 4 of an ice house 5, the latter being more or less chematically indicated in the drawings.

The two posts 2 carry respectively, up right guides 6 which may be in the form of longitudinally grooved timbers, these guides being secured to the uprights 2 at suitable intervals by strips 7 or in any other appropriate manner. At the opposite or front sides of the posts 2 are cross bars 8 there uniting the uprights and preventing them from spreading and also serving as supports for upright slats 9, which latter, however, may be arranged in the form of a solid wall, instead of being spaced slats, as indicated in the drawings. The guides are ar ranged to receive boards 10 in upright series forming a wall opposed to the wall made up of the slats 9, the said slats 9 andboards 1O 9 being sufficiently spaced. apart to:-provide a? well.

On the base 1 in advance of the uprights,

2 is another well formel of uprights 11 erected on the crossbeams 12 of the basic frame 1 in advance of the uprights 2. The A uprights ll have their inner faces provided "with longitudinal guide strips 13 forming channels, and the uprights2 have similar V longitudinal guide strips 14 constituting channels. ,"at their upper ,ends to the uprights 2 by beams 15 to stiffen and strengthen the parts and near the top and bottom the uprights 11 are joined by cross strips 16 carrying up constitutes their sprocket wheels The-uprights 11 are connected right slats'17 forming a wall, similar to the wall made up of the slats 9 and constituting the rear wall of a well at the delivery-part of the conveyer structure when conveying" ice from theicehouse toa point'of depo 1 sition. K

' The two wellslare joined at their bottom ends by a; substantially semi-cylindrical apron 18 having end members 19 each carrying a curved guide 20. a

. Near the top of the uprights 2 on 'what front portions are journal blocks 21 inwhich is mounted a shaft 22,

shown in Fig. 1 as having one end 23-extended, so that power. may be appliedthereto, if desired, by means'of apulley or in any other suitable manner.

Mounted on the shaft 22 near the bearing blocks 21 are sprocket wheels 24 andthese carry endless -.sprocket chains 25-extending through the Wells and underneath the guideblocks'20, the strips 13 and'14: also serving as guides forkthe" sprocket chains so. that these chains each have twosubstantially vertical runs.

Carried by certain of the sprocket links of the' sproc ket chains are'flights 26, each comprising, end brackets 27 made fast to appropriatelinks of the chains, and between-the chainsthese flights are of sinuous form. Each flight may be made up of a single strip of metal bent upon itself, with the bends in spaced relation to. form elongated and some what flattened alternating loops. The flights are supported solely. at the ends and are 7 of suflicient width to readily carry a cake of ice of customary size, the wells through which the flights travel being also. of suitable cross sectional area to permit the passage of A the cakes of ice therethrough.

' the inner faces of the slats 9 and guided therebyand bythe adjacent strips114. The

I bars 28 arecapable of traveling up and down Adjacent to the wall ma 1e uplof theslats.

9 and within the well between the uprights 2 is a guide member composed of curved barsv 28 fast to the ends of strips 29 movable along in the well in which they are located and bow'toward the rear portion of the conveyer structure,'that is toward the ice house when the con'veyer structure is in position. The

4 guiding frame having the bars 28 is supported by a rope or cable. 30 carried around a pulley 31 mounted loose upon the shaft 22 so as to rotate independently thereof and the cable is continued from the pulley 31 downwardly between the two walls made up of the slats 9 and 17 and to a Windlass 32 having a crank .33 and, pawl-and-ratchet mechanism 34: within convenient reach of an operator, so that the guide bars 28 may be raised or lowered as desired. The bars 28- are so lo the loops, thus permitting the flights to move lengthwise of'the guide-bars 28 without interference by or with them.

The basic member 1 isprovided with a longitudinalbeam 35 between the front" and rear beams'of the frame, and rising from the beam 35 are tubularp'osts136 secured at their upperends to a cross bar 37 fast in the uprights 11. "Telescoping in theposts 36 are rods 38 having angle extensions 39' at-their upper ends carrying a cross bar 40, which, at the ends, is made fast to slides 41 so spaced as to moveiin front of the front edges of the uprights 11.' These'front'edges have dovetail upright guides 42 thereon in which engage dovetail tongues13 extendinglength 11 carry a ,serie's'of rods' te. so bent and shaped that they present a-curved front toward the outer portion'of the well inclosed by the uprights 11 and: wall17. These rods 45 are; so situated that they move; freely through the loops of the flights 26, orthese flightsmovefreely along the rods 15 without interference with or by them. Y Y

. Carried by and extending between the slides -11 below the cross bar40 is a-rod 6 to which is hinged meansof a strap-4L7 one end of atelescoping-chute4e8 made up of two series ofslats 49 'and'50 respectively. ar-

- ranged alternately. This permits the chute to beelongated or shortened as may be found desirable. Thehinged section of the chute 48 is carriedby a chain oricable 51=rising to a pulley block-52 carried by a fixed strap 53 connecting the upper ends'offthe beams 15 and extending from one beam to-the other. Thechain orcable. 51 andpulley 52 may be arranged so as to permit raising and. lowering of the chute to accommodate it to differc'atedwith reference to the loops'of the flights as to enter between the side walls of entelevations of vehicles or carriers conventionally represented in Fig. 2 by a box car 54, but which, it will be understood, maybe replaced by any suitable transporting means. The slides 4l'are connected at their up er ends by a strap 55 carried by a chain or ca le 56 which may be connected to another pulley 57 similar to the pulley 52. a

The doorway 4 of the ice house 5 may be closed by' removable members 58 to allow for the lower level of ice in the ice house, represented in Figs. 2 and 3 at 59.

When the level of ice inthe ice house is considerably above the level of the floor .of the receptacle 54 or accumulation of ice therein, no power is needed to cause the delivery of ice once deposited from the ice house onto the flights 26 to the receptacle 54, the operation being performed by gravity. An operator moves the blocks of ice from the ice house onto an adjacent flight26 in the well back of the wall 9 and the weight of the block of ice is suflicient to propel the endless carrier made up of the chains 25 and flights 26 toward the apron 18, subsequent blocks of ice followingas rapidly as the flights present themselves in position to receive the cakes of ice fromthe ice house. Then the cakes of ice travel through the apron and ultima-tely reach the lowest" part of the latter from which the flights rise and consequently a flight propelled by acake of ice into the apron 18 receives the preceding cake on its opposite face and then becomes an elevating flight for the cake of ice, lifting it until the cake of ice is engaged by the curved or otherwise suitably shaped rods 45. As the endless carrier continues to rise, the rods 45 propel the cake of ice toward the chute 48 and expel the cake of ice from the well through which the rising flight of the carrier travels. The chute 48 is always positioned so as to slant downwardly from the front of the apparatus toward the car and consequently the discharged cake of ice naturally gravitates to the car. So long as the level of ice in the ice house is sufliciently high above the receiving portion of the car, the

travel of the conveyer is entirely automatic, the weight of the ice providing the propelling impulse. When gravity can nolonger be utilized, power must be applied to the shaft 22 to actuate the conveyer.

The apparatus is equally useful for filling the ice house from vehicles transporting the ice to the ice house. The cakes of ice are moved along the chute 48, which in this case may slant downwardly, toward the conveyer structure, and the ice is directed by the rods 45 onto the flights 26 as the latter move downwardly into the forward well, the direction of movement of the runs being reversed from that first described, Now the cakes of ice are directed into the apron 18 and rise in the well adjacent the ice house,

with thedirection of movement of the'flights in conveying the ice from or toward theice house. The adjustments of the carrying means for the directing or discharging bars is provided for in the Windlass 32 controlling the bars 28 or the pulley 57 controlling the bars 45, while the direction of inclination of the chute 48 isdetermined by the adjustment of the slides 41 and of the chain or cable 51.

By making the main frame of the machine in two upright portions spaced apart but relatively close together and constituting wells for the conveyer, the device is made very compact so far as its extent from the ice house is concerned, wherefore the conveyer is useful under conditions where the available room is limited and the space in which the conveyer must be operated is narrow. The conveyer has two upright and substantially parallel runs, one traveling downwardly in one well and the other traveling upwardly in the other well and both runs being active. The arrangement is such that the conveyer may be used for carrying ice, or any other commodity or containers housing commodities, and transporting such commodities in either direction.

The reversibility of the conveyer is made possible by the upright arrangement of the two runs of the conveyer and by the association with the two runs of separate direction changing devices, each capable of directing material into or from the conveyer. If, for instance, the down run of the conveyer has the direction changing device associated therewith arranged to direct material into the conveyer, then the direction changing device associated with the up run of the conveyer is arranged to direct material from the conveyer. The chute provided is connected with the corresponding direction changing device and is adjusted up and down therewith, while the other direction changing device is adjustabe up and down independently of the first named device. When ice or other commodity is directed from the storage house to a vehicle or the like, it is directed by the chute into the vehicle and, when the material within the storage house is higher than the point of deposition in the vehicle, the operation of the conveyer may be entirely automatic, due to the action of gravity. When the level of the commodity in the storage house is too: lowwithrela-tion to the vehicle to admit-of propulsion of the conveyer by gravity, other- The sinuous or "undulatory flights permit the use of direction changing; devices .hav ing 1 fingers, which, the present instance,

are shown. as formed of wiresjorj bars "bent into appropriate 7 shape.- These fingers are solocated as to "extendinto thepath offthe flights from: the rear of each run of the cons veyer carrier, the fingers entering'between feeding fingers to be supportedback of the respective flights andextend into the paths of 'theflights toward the fronts thereof be-V yo ndithe mid line oftravel of 'thei conveyerflights so that the same feeding fingers or I direction changing devicesrmay be usedv for 7 of the endless carrier.

causing theioe or other commoditytoinove ontoithe flights or-to move from 'theffiights in accordance with the directions of travel The runs offthechain have been referred to assubstantially vertical; Such position v house to a vehicle, the cakes are fed from need not be strictly adhered to, since under some circumstances-the runs may. be tilted; The compactness of the structure is due largely to the fact that the runs oftherchain are substantially parallel whether the runs be upright or nearly so, or whether they be tilted to a material extent. v When ice is to be, delivered from-the ,ice

the ice houseedge onxso as to engage the fingers 28 above aflight of the f carrier already below the upper ends of'saidfingers 28L The curved or bevel form of the fingers causes the cake ofice to move on edgeonto the flight receiving it, and at the same time prevents it from passing in the well far enough to permit "the next cakein orderto I enter under the edge of the, next higher flight, wherefore, when the: first cake of-icecompletely enters the, well, the next higher flight, has'ubeen lowered :sufiiciently to cause the second cake of ice to enter on top of it and tilt as it follows the'fallingflight to come into the path of the third cake, causing thejlatter to be directedonto :thetop of the next succeeding flight? The ice cakes are therefore automatically directed onto the proper flights in order, so'that the feeding,

, so far' as the entry onto'the. fiightsisconcerned, iswholly automatic, andit is'impos 'siblevfor more than one cake to .get' onto the carrier betweentwo; flights and to interfere withthe motion of the flights or check the carrier. H
